My husband and I have a 4 hour drive (maybe longer since we will be making stops) with our 1 month old baby. On Sunday she’ll be 5 weeks. I am concerned of the drive if the roads are bumping I don’t want her to shake or bounce around a lot. Tips? Should I put a neck pillow around her? Or a blanket in the car seat with her? Also, have you traveled with a newborn before? Would you recommend a binky?
